Gentrol IGR will not kill insects, it only prevents them from reproducing. You should use other insecticides, such as Suspend SC, in conjunction with the Gentrol Concentrate. In general, if you use the recommended products together as advised you will start to see a reduction in insects within a week or two. However, it may take a month or so so see full eradication.
